Abstract

L'invention concerne un onduleur. Dans cet onduleur, en parallèle avec le circuit série formé de deux thyristors 2, 3; 4, 5 devant être amorcés en alternance, se trouvant branché un circuit oscillant LC 12, 13, dimensionné de telle manière que, lorsque deux thyristors 2, 3; 4, 5 sont amorcés simultanément, le circuit oscillant 12, 13 commute dans un certain état sous l'effet du courant de court-circuit, et, lors de sa commutation à l'état opposé, en retour, lesdits thyristors sont désamorcés par la chute de tension appliquée à la diode unidirectionnelle respective 6 à 9. Application notamment aux onduleurs d'alimentation du transformateur à haute tension d'appareils de radiodiagnostic.The invention relates to an inverter. In this inverter, in parallel with the series circuit formed by two thyristors 2, 3; 4, 5 to be started alternately, being connected an LC oscillating circuit 12, 13, dimensioned in such a way that, when two thyristors 2, 3; 4, 5 are started simultaneously, the oscillating circuit 12, 13 switches to a certain state under the effect of the short-circuit current, and, when it is switched to the opposite state, in return, said thyristors are deactivated by the voltage drop applied to the respective unidirectional diode 6 to 9. Application in particular to supply inverters of the high-voltage transformer of radiodiagnostic devices.
